Minors Shouldn't Be On Geosocial Platforms
It's hard enough as is to separate the youth and adults each doing their own things in this community, and there are frighteningly frequent cases of grooming and other predatory behaviors that slip through the cracks.
Hiding people in different age groups from each other was a good suggestion I saw. However, there is no way to keep people from just lying about their ages if minors are allowed, as many non-adults don't have id's that can be shown and checked.
Meeting random people online sometimes already leads to bad situations, but on Geosocial applications, creeps who use them are already near the people they find, making them that much more dangerous.
All Geosocial apps should be 18+ at the very least!
